Confirmed still an issue in 4.26.1
Reproduction is trivial, start a new project, create a class, give it some variables, make a class variable anywhere for this new class, drag off to create the ‘get class defaults’ node, observe how it doesn’t work when you try to hide them either via the ‘hide unconnected pins’ or by unticking the variable boxes.
Given it’s an engine bug, the solution is to roll back to an earlier version or wait for an update.
Or as it’s probably not worth it, in the meantime you can stick the node inside a function in a function library/separate function/collapsed node or similar.
For what it’s worth, I’m on Windows 7
